在小麦背景中离果山羊草3C染色体具有优先传递的作用。当离果山羊草3C染色体处于单体状态时会导致后代不含有杀配子染色体的配子中产生包括缺失和易位等染色体结构变异。簇毛麦4V染色体携有抗小麦眼斑病和全蚀病基因。为进一步利用簇毛麦4V染色体上的有益基因,利用染色体C-分带和基因组原位杂交分析,从普通小麦-簇毛麦4V染色体二体异附加系(DA4V)与普通小麦农林26-离果山羊草3C染色体二体异附加系(DA3C)杂种后代中选育出小麦-簇毛麦纯合易位系T4VS·6AL。该易位系为杀配子染色体诱发形成的非补偿型易位;易位系T4VS·6AL高抗梭条花叶病,是小麦抗病育种的新种质。
In the wheat background, the goat Leymus chinensis 3C chromosome has the preferential transmission role. When the 3C chromosome from Aegilops tauschii is monomeric, it will result in structural variations in chromosomes including deletion and translocation in gametes containing offspring chromosomes. The cluster chromosome 4V carries anti-wheat leaf spot and eclipse genes. In order to further utilize the 4V chromosomal genes of H. villosa, chromosome 4 C-banding and genomic in situ hybridization (SSH) The homozygous translocation line T4VS · 6AL of wheat-cluster-wool maize was bred from the progenies of the hybrids of DA3C in Aegilops tauschii. The translocation line is an uncompensated translocation induced by the gametocidal chromosome. The translocation line T4VS · 6AL is highly resistant to shuttle mosaic disease and is a new germplasm for disease resistance breeding in wheat.
